Multi-surface Cooler
A type of passive cooler that allows both airflow between the laptop base and cooler, as well as, between the base of the cooler and the users's lap. These laptop coolers are well suited to laptops that have vents on its base because it prevents these vents from being blocked regardless of what ever surface the laptop is used on. Therefore, these multi-surface coolers are suitable for use on desk, lap and uneven/soft surfaces (couch, bed/duvet, carpet) and outdoors.
